Cal OSHA expects dental practices to evaluate employees’ need for PPE. A dental employer must provide and ensure use of respiratory protection for employees exposed to procedures that aerosolize saliva or other potentially infectious materials, unless a patient has a negative test result after self-administering an OTC COVID-19 antigen diagnostic test on the same day and prior to the performance of dental procedures which aerosolize saliva or other potentially infectious materials. A respiratory protection program includes the provision of respirators and medical evaluation and fit testing of tight-fitting respirators to staff occupationally exposed to dental aerosols. A written program and staff training also are required.
Below is information on other types of NIOSH-approved respirators, how to complete a medical evaluation and fit testing and compliance documentation. Resources are available for dentists who want to conduct the required fit test themselves.
